Abstract

La présente invention concerne une forme du filet mécaniquement plus résistante et de meilleure résistance à la fatigue. Le fond de filet est taillé selon plusieurs rayons de taille décentrés. Deux au moins des surfaces du fond de filet résultent de rayons de taille aux longueurs supérieures à la troncature du fond. Ces filets, utilisés dans les configurations double pas, permettent d'augmenter la résistance du raccord et de réduire le nombre de tours de blocage et de déblocage.
